Thanks to all who responded. There were several good points about the
code itself, all of which both helped and work.
I will likely use Alan's example because I find it the most lucid, but
the other suggestions are good signposts to other ways to do the same
thing (but right, as opposed to how I was doing it).
Lie's suggestion that I didn't understand the calling structure of
Python was right on the money, and his included link helps with that,
too. Thanks again.
The problem with that approach is that you're still making unnecessary
recursive calls. The problem isn't a recursive one, so why take the
risks that artificial recursion imposes.
You need a loop, and putting a while True: around the whole thing
solves it nicely. Don't *call* the function again, just loop back and
do the operation again. That's what loops are for.
Incidentally, learning about recursion is a very good thing, and
useful. I just don't think it's the right answer here.
